The Next Generation

Chapter 1: The Arrival

These were times of peace and prosperity for Thundera. Mumm-ra had finally been defeated, and the world was finally at peace. It was an extremely joyous time for Lord Lion-o, having finally married the love of his life and expecting his first cubs. However, certain surprises are watching the Thundercats, waiting for the perfect time to strike.

It had been seven years since Mumm-ra and the lizard army had been defeated by the Thundercats. Seven years since Thundera was rebuilt. Seven years since nearly all species united with each other, as they once had been during primordial times.

And in those seven years, the Thundercats had become closer than they had ever been. Every one of them grew up and married, starting families of their own to continue their ancestors' legacies.

Shortly afterward, Lion-o had managed to win Cheetara's heart. Tygra had met a white tiger named Taulia and had a son named Tiro, and were expecting a second child in a few months. Panthro had finally married his sweetheart Unciana, and they too had a son they named Pardes. Wilykat met a jaguarundi named Rundija, and were engaged to married in a year. Wilykit married her childhood crush Bobcat, and were currently trying to have a child.

Now, Thundera was preparing to welcome the next heir to the thrown. Five years after the city was finally rebuilt, Lion-o and Cheetara married and were expecting twins, to which Cheetara was currently giving birth to, and to why Lion-o was currently pacing outside the bedroom doors.

"How much longer?" He asked, getting irritated at the fact that he was not able to see his wife.

"She's in labor, Lion-o. It could be an hour, it could be a day," Tygra explained as he sat back in his chair. Lion-o shook off his brother's words and continued pacing.

The young lord was, indeed, very nervous. Due to them being different species of cats, it took two years before Lion-o and Cheetara manage to concieve a child. It was also because of these events, Lion-o constantly worried about the things that could go wrong. He was also stressed at the lion elders' requests, constantly being "reminded" of the chance to take a lioness mistress, someone who would be able to produce a full-blooded king.

Nobody, however, was prepared when the news came that Cheetara was not expecting one cub, but two. Lion-o, though, was very thrilled, knowing that he'd have two cubs to share his and Cheetara's love.

He was snapped out of his thoughts when the midwife burst through the doors, "My lord, the children have been successfully delivered. Congratulations! And the Lady Cheetara is just as fine."

Lion-o looked over at her, suddenly getting stunned as reality washed over him. "Could I go see them?"

"Of course, my lord!" The midwife smiled as the king slowly waltzed into the room. He was shortly followed by Tygra, Panthro, the twins, and Snarf.

Lion-o peered around the room. The curtains were drawn, letting in the golden sunlight. And sitting upright in a large bed, was Cheetara. In her arms were two bundles. She looked up and cast a tired smile at her husband, "Lion-o, come see our children."

Obeying his wife, the lion made his way across the room, peering down at the two beings in her arms. "And they are?"

"A boy and a girl."

He peered down, a single word coming from him: "...Wow."

The twins had both favored their parents. The boy had Cheetara's fur, along with her pink facial markings and her blonde hair, though his was thick and spiky like his father's. The girl had brown fur like Lion-o, along with brown facial markings and a tuft of soft red hair.

Tygra patted his little brother on the shoulder, "Congrats, bro. You did it."

They all took a placed around the bed, admiring the next rulers to the kingdom. It was after a moment of silence that Wilykat finally popped the question, "What're you going to name them, Lion-o?"

Lion answered, "We've decided on Chiro and Claudea."

"Chiro," Panthro repeated, "Future lord of the Thundercats."

Kit cleared her throat. "Don't forget there's also Lady of the Thundercats!" She answered, in a way to remember that there was also another baby there. It succeeded in everyone laughing.

Surprised by this strange noise, the twins opened their eyes. Tygra laughter only more as he took notice, "Like father, like son!"

It was true. Chiro had gained his father's teal eyes, while Claudea had gotten her mother's ruby orbs.

Everyone smiled as they continued to gaze down at the two new lives, knowing that the two would be taught well to lead, one day.

However, unbeknownst to the king and queen, two cats were also busy talking about the future heirs. Though these two were not discussing the cubs in a good way, but rather like they were a burden, a mere annoyance.

One was a young black jaguar. She had a blue coat with a jet black mane, along with several spots running across her stomach. Her bright red shorts and tank top were covered by her dull grey cloak.

"Two of them? Are you sure?" she asked, dumbfounded.

"Very sure," the other cat answered, this time in a gruff male voice. The male was a dark brown sabertooth cat, with a brown mane that extended into a beard, and dark brown eyes. One noticeable trait about him was that he had a large jagged tooth sticking out of the left side of his mouth.

The jaguar's bright amber eyes burned fiery pits into the sabertooth.

"Do you realize what this means, Grune? It would be hard enough with just one, but with two brats in the way, it'll be a millenia before I make Thundera mine!"

The sabertooth, or Grune, smiled, "What about that son of yours, Onsa? Surely you've thought about where he comes into play?"

The jaguar known as Onsa glared at him, "Where you getting at, Grune?"

"I've heard that the queen's had one son and one daughter. Don't you see, Onsa? If the boy is killed, and he manages to win the heart of the princess, then Thundera will fall straight into your hands!"

A look of shock crossed Onsa's face as she considered Grune's words. Then her face twisted into an evil snarl.

"Yes, I can see it. He will lead us to victory!"

"Of course he will! He'll kill the Thundercats, and Mumm-ra will finally be awakened!"

Onsa laughed, "Oh yes! I will finally get my revenge against those bastards, and I will take what's righfully MINE!"
