There's not too much to say as to why he's on the team. He's Lebron... He's the goat. If i were to go on for as long as I could, I could go on forever. The goat needs not my praise for his consideration.
I don't really know Z too well. Heck, I haven't even seen "Antz." But, I mean... look at him. He looks like a guy who won't let his team down. I think he'll be an asset to the dodgeball team.
Full disclosure, Tobor, or "T.O.B.O.R" is here for moral support. We already have enough man-power on the team. He's here to keep everyone's spirits high. He'll prove he's more than a just a figment of imagination.
Donkey Kong is here to target those pesky, flighy ones on the enemy team. He may not be the best athelete, he's quite slow. He makes up for it in pure power. He'll throw those dodgeballs so quick, that he'll get their strongest ones out before the game even begins.
Another goat, even rivaling Lebron. Faker is here as the team strategist. He won't just have us win the game. He'll have us lose about 50% of the time in regular season and then pick it up for playoffs and barely have us make it to worlds, only for our team to absolutely dominate and continue to stay on top because Faker at worlds is uncontestable. They don't call him the "Unkillable Demon King" for nothing. All roads lead to him.
