Last time on Dragonball Super after the battle with Beerus Goku had trouble transforming into a Super Saiyan God and sought Piccolo for help. Giving advice Piccolo instructed Goku to use the Pendulum Room to fix his own internal problems that kept him from transforming. Meanwhile Vegeta after some motivational help from his Daughter Bra and going through his own thoughts finally decided to get some outside help to become stronger. But unknown to our heroes a mysterious force is planning their downfall. How will things develop from here and will our heroes be able to grow stronger? Find out today on Dragonball Super!

As he opened his eyes Goku found himself in a strange but familiar forest. "Hmm apparently this place is supposed to hold the thing that keeps me from becoming a God. Well no time like the present might as well explore and see what i can find." Walking around Goku soon found himself near a river and immediately his stomach rumbled.

GROWL

"I hear ya stomach it's been a few hours since we ate. Well can't work on an empty stomach that's what Grandpa used to say, or maybe it was Goku don't eat all the food could have been either one. Well time to start fishin." Stripping down to his undergarments Goku quickly dived into the river and began to hunt for fish. After about an hour Gokus stomach was full after a couple helpings of giant fish. "Ah now that hit the spot. Well better start exploring not gonna get anything done sitting here."

Getting up Goku continued to explore looking for what he had yet to accept. Finally he saw a light in the distance and decided to head towards it hoping to get some answers. After passing through some trees Goku looked to see an old man in the distance picking up some heavy firewood. "Maybe he can help me." Walking closer to get a good look at him Goku was about to announce his presence when suddenly he recognized this man someone he hadn't seen in decades. The one man who he loved as much as his wife and children. "Gr-grandpa?"

Meanwhile

Vegeta had made it back to Capsule Corp with Bra who went to go play while him and Bulma talked. Greeting her husband Bulma kissed him on the cheek. "I hope you're feeling better now Vegeta we were all worried." She said. Smirking Vegeta quickly grabbed a bite to eat before replying. "Heh of course I'm the prince of all Saiyans a little problem won't stop me." Chuckling Bulma couldn't help but be amused by her husbands attitiude. "Well at least your egos back."

For the rest of the day Vegeta had acted like his regular self training with Bra in the gravity room as she wanted and as the day ended Vegeta had planned on how to find the teacher that he desired.

Meanwhile on a Mysterious Planet far into the Galaxy

The three figures slowly began to walk into dimly lit lab revealing themselves to be Frieza, King Cold, and Cooler all who were greeted by the head scientist. "My lords it is an honor to be within your presence how may we serve you today?" Taking a quick glance "How is the project coming along?" Frieza asked. Bowing in terror the scientist nervously responded. "Um well that's the problem while we were able to get it working for the people you requested it to be used on their power is just to great for the machine to keep them trapped. In short they would be able to break out any time they so desired."

Looking down in frustration Frieza outstretched his finger and lit it up right in front of the scientists face who was now sweating bullets. "Do you know the price of failure Doctor?" As Frieza prepared to fire the scientist began to plied for his life. "Lord Frieza please wait! What about if we were to modify the machines instead of creating a nightmarish realm we could make it the perfect fantasy for the victim so that way they would want to leave incapacitating them as you wished?!"

For a few moments the room was dead silent as the scientists prayed for their life. Thankfully luck was on their side as Friezas finger settled down and the emperor spoke. "Fine I'll give you one last chance to get this right, but fail me again and I'll destroy not only you but your entire family." And with that the three Colds left much to the relief of the scientists. Walking down a hall Cooler mockingly spoke up. "You might want to treat your subjects better Frieza who knows maybe they'll use it on you one day."

Not one to let the comment go Frieza fired back. "Or maybe I'll just use to get rid of you after this is over would save me the trouble to dealing with you." Immediately the two brothers locked eyes as sparks flew daring either one to make the first move. Sighing in exasperation King Cold quickly broke up this feud before it could get worse. "My sons there will be time to settle this trifle feud but for now we have a Saiyan menace to destroy so i suggest for once you two get on the same page."

Looking away from each other both brothers cooled down and continued to walk down until they reached a throne room which housed a single figure who stood up from his throne and walked towards the three. "It is good to see you again father." Nodding Frieza walked up to the figure putting his hand upon his shoulder. "It is good to see you as well my son Kuriza."

Meanwhile back on Earth with Goku

Goku ran up to his Grandpa and scooped him up into a hug. "Oh it's so good to see you." As Goku continued to hug the closest thing to a parent Grandpa Gohan spoke up. "Um it's good to see you to sonny, but who exactly are you?" Dropping his Grandpa in confusion Gokus shoulders slumped as he pointed to himself. "Grandpa it's me Goku your grandson remember?" Looking at Goku in confusion he looked over him for a second. "Look here you may look a lot like my Grandson but you are certainly not him. My Grandson is sleeping in his room during the Full Moon tonight."

Taking a moment to look around Goku saw a house exactly like the one he used to live in and a small house next to it. Soon the pieces all came together and Goku as if a light bulb went off in his head and his face morphed from confusion to horror as he began to whisper to himself. "This is that night. Now i know why i was sent here. The night i lost Grandpa."

Not hearing Goku Gohan decided to go back to his choirs picking up the heavy firewood. "Now I don"t know who you are but you seem like a lost and confused soul. How about you spend the night here with me and my Grandson and we ca- AH!" Dropping the firewood Gohan clutched his back in pain. Running up to Gohan Goku tried to help him when he heard a voice. "Grandpa. Grandpa what's wrong?" Running out of the door to help his Grandpa was Goku from when he was a kid wearing his old blue attire.

Panicking Gohan futility tried to wave off his Grandson. "Goku go back inside and go to bed now you know what time it is!" Ignoring his order both Gokus huddled around Gohan trying to help him up. Noticing his older counterpart Kid Goku looked up to greet him. "Hey mister who are you and how do you know Gran-." Unfortunately while looking up Kid Goku spotted the Full Moon and his eyes shifted to red as he stood there like a statue. "Goku stop don't look!" By this time it was to late. As Goku continued to look his body began to bulk and hair grew on his chest.

Stepping back holding his Grandpa up Gokus mind swirled as he realized just what Piccolo was talking about. "The day I transformed and the day I-I killed Grandpa. Soon Goku was now a full grown Great Ape ready to smash everything in sight. "Looking in horror Gohan tried to move but was unable to due to the pain in his back. "Get out of here now sonny. If i know Goku he'll destroy this entire forest.

I'll try to hold him off just leave before you get killed." Gohan tried to warn but it was to late as Goku set his sights on the two and lifted his foot. Sitting his Grandpa down Goku looked up at himself. "Stay here Grandpa I'll save you this time." Powering up Goku flew up on the descending foot and caught it with ease much to Gohans shock. Pushing him off Great Ape Goku toppled over crashing to the ground with a thud. With determination to fix his greatest failure Goku watched as the Great Ape slowly got up now even angrier.

ROAR

With a mighty roar the Great Ape shot out a blast from his mouth at Goku engulfing him in it. As the blast stopped Goku was still there completely unharmed by the attack. Outstretching his hand Goku was dead serious unwilling to lose.

"I'll make sure you stay down for the rest of the night." With a simple Kiai Great Ape Goku was struck in the face and crashed to the ground once more now out cold. Looking up in shock Gohan could not process what was going on. "But how I've never heard of someone so strong to be able to do that to Goku when he's like that."

Coming down Goku looked at his Grandpa with many emotions such as Guilt, Hope, and Relief. "It's a long story Grandpa." After an hour Goku had filled Gohan on how he first met Bulma and the history his battle with Beerus. "So, my baby boy became a Universe saving hero and had children. I knew you would do some great things Goku but i had never imagined it would be to that extent. But why are you here Goku?" Gohan questioned.

Sighing Goku had explained what he left out revealing that Gohan died tonight because of him and how for decades he never knew until his fight with Vegeta where he first saw a Great Ape and begun to remember his time as one. Hearing this Gohan pondered this information. "I had hoped you would never find out about your transformation I knew it would devastate to know about the monster inside of you."

As Gohan continued to think Goku decided to continue. "After the fight with Beerus I was unable to transform into a Super Saiyan God and so sought out Piccolo who told me that my mind refused to accept something i had done and used the Pendulum Room to send me to what it was and that was... the night I crushed you." Seeing his Grandpas shocked face Goku immediately hung his head in shame.

For a few minutes the area was silent until much to Gokus surprise he felt Gohans hand sit itself on his shoulder. Looking up Goku didn't see the anger or disgust that he had expected to see from his Grandpa but instead saw warmth and comfort. "Goku I know you must feel pain and regret at what happened but if i can forgive you for killing me then you must forgive yourself. You must let go of this guilt you feel my Grandson it was not your fault."

Hearings these words of comfort to his years of guilt once again just like his first reunion with his Grandpa Goku hugged him tightly as tears began to flow from his eyes. "I missed you so much Grandpa." Goku lamented. Hugging his Grandson back he allowed Goku to let it all out. "I couldn't have asked for a better Grandson remember that Goku."

As the time passed Goku and Gohan chatted about many things with Goku telling Gohan about his Granddaughter Pan. "To think for years i wouldn't even have a son and now I find that I will have a Great Great Granddaughter." As the sun rose up Goku knew that it was time to go. Hugging his Grandpa one last time Gohan picked up the now normal Goku and walked inside preparing for another day."

Looking at the old house that he used to live with his Grandpa Goku closed his eyes and began to focus and soon he was back in the Pendulum Room with Piccolo. "So, were you able to succeed Goku?" Clenching his fists Goku thought about the day he crushed his Grandpa and remembering his words finally let it all go. With a mighty roar Goku easily transformed into a Super Saiyan God nearly blowing Piccolo away from the sheer power. "You tell me Piccolo."

With his conscience now cleared and his mind now at peace Goku has finally transformed back into a Super Saiyan God. But what about the four Colds and their plan against our heroes and who exactly is this teacher Vegeta spoke of? Find out all these and more next time on Dragonball Super!
