Mikey's POV
"MIKEY!" I giggled at the sound of Raph screaming at the top of his voice. He must have realised that his bandanna and sai handles are painted pink. I would have painted his room pink while I am at it, but I still have to mind my injuries, though they are gradually healing, since Donnie might go mother-hen on me or something. Speaking of pranks, I am doing them, not just because I am in the best mood, it's also because I am nervous they might suspect that the 'stranger' is me. I know that it's too soon for them to know, but I just feel uneasy, as though they might find out about it after 1 second or something.

So, I am playing pranks to not let my brothers suspect a thing. If I just act like my usual goofy self, they would surely, not notice a thing. Although this might work for some time, I know that it will be a matter of time before they found out. Speaking of which, I just remembered! Master Splinter told them to be wary of this 'stranger'. I will have to be ready since my brothers might do something to him/me. I might need a costume, since I might risk exposing myself to the guys. Let's see if I have one...

Normal POV
As night falls, the 3 turtles left the lair, after giving Mikey specific orders to stay in the lair. "Awwww! When can I go for patrol with you guys again! Being in the lair all the time is sooooooo boring!" "Sorry Mikey, you are not quite ready yet. Don't worry, you will be ready to be patrolling with us after about 1 to 2 weeks." "Seriously dudes?" "Sorry Mikey, but we will be back as soon as we can, ok?" Leo tried to convince Mikey. "Ok, fine..." "Thanks Mikey." The 3 turtles then went out of the lair.

"Ok. Let's do this." After he made sure that the 3 turtles were quite far away from the lair, or possibly topside, he took out the hood. The hood was found in the dumpster a few years back. He never showed his brothers about it because he thought he might use it for some superhero thing or some secret thing he might do someday. He put on the hood and masked himself after he slipped from the lair so that if he really did get caught by his brothers, they would not recognise him straightaway. After he put on his costume, he attempted to find a manhole cover to go topside. While he did that, he minded his healing injuries. As they are healing, he can run faster than before, but not too fast.

"Ok, so there is a canister of mutagen here too, right?" "That's right." "Well I don't see anything here." "Have patience Raph! It's got to be here somewhere!" "Leo's right! The Mutagen Tracker has never gone wrong before!" "Well, I don't see anything! The Mutagen Tracker must be busted!" Before Donnie can answer, Fishface suddenly came, with hordes of Foot Ninjas. "Looking for this?" "Fishface! What are you doing here? Why are you here?" "Raphael, how nice to see you again, after our last battle. I would normally kill you since I have this opportunity to make your end swift, but Master Shredder wants his enemies brought to him, together with your rat master, so I hope you are prepared."

As he finished, hordes of Foot Ninjas burst out and attacked Donnie and Leo. Fishface went to attack Raph, since he has a bone to pick with Raph.

As Mikey went topside, he suddenly got the strangest feeling that his brothers are in trouble. He then remembered what Master Splinter said.

Flashback
"Always trust your instincts, my sons. You never know when your instincts may become handy, during a battle or in everyday life."

Present
Remembering that sentence, he chose to follow his instincts. When he approached an alleyway, his instincts become stronger. He then saw a battle between Fishface, Foot Ninjas and the turtles! He chose to help Leo and Donnie first, since they can help Raph to battle Fishface. Raph could get hurt fighting Fishface alone, since Fishface's venom proved to be quite toxic the last time he used it. After pondering for a moment, he used his bow and some arrows he grabbed out of the dojo and began to shoot at the Foot Ninjas.

Leo and Donnie stopped fighting for a while, noticing the number of Foot Ninjas dwindling due to the arrows shooting at them from the rooftops. "Great, the mysterious guy must be back. I wonder what his motive is though?" Donnie asked out loud. Leo roaming eyes found a hooded figure on a rooftop quite near them, holding what seems to be a bow. Leo guessed that it must be the mysterious archer. "Just who is this guy? Why is he helping us?" Leo wondered.

"Hey, can you give me some help here?" Raph asked the other 2. They pulled themselves together and turned to face Fishface. "Ah, I see that the Foot Ninjas are defeated." "Come on Fishface, face us!" Raph shouted. "All right, I will promise you that your end will be swift." He lifted his metal hand to strike, but Mikey was not quite done yet. "Arrows? What kind of trick is this?" As he was distracted by the arrows, everyone striked hard at Fishface. Fishface then started to retreat. "You haven't seen the last of me, turtles." He sneered before he vanished into the shadows.

"Whew, I am glad that's over." "Yeah, I gotta say, speaking of which, anyone knows who this mystery helper is?" "I don't know, but I saw him on a rooftop, over there." "There? All right, let's find him! I got some questions to ask him!" When they started to approached the rooftops, Mikey panicked and started to dart from rooftop to rooftop. "There! I see him!" When Mikey reached another rooftop, he was about to heave a sigh of relief when suddenly, Leo came out of no where and caught him on the shoulder.

"Alright sir, can you answer some of our questions? First of all, how do you know about us?" "That, I cannot answer, turtle. I am a helper, I help people who are in trouble." "Who are you anyways?" "I am...the Night Guardian." Mikey then darted away and disappeared into the shadows before anyone can question him further or catch him.

Mikey's POV
Oh shell, I hope my disguised voice works, or not, my bros are sooooo gonna find out what I have been up to. I called myself the Night Guardian because I think it's cool. I would call myself the Turtle Titan but that would be too obvious; everyone would know straightaway. Anyways, better get back to the lair, don't want anyone to find out that I was missing from the lair.

Normal POV
"Seriously, what was that all about?" "I don't know Raph. This...Night Guardian...there's something about him that was kinda familiar, I just can't place where." "Well, that mission is a bummer, we did not get any mutagen, that mutagen crashed onto a wall by Fishface." "Ok, we better get back to the lair though. Let's not attract more Foot here." "Whatever you say, Fearless." Raph smirked at Leo's annoyed glance before proceeding into the Shellraiser with the other 2.
