My main Chao in the Chao Garden are:
Chaos 0- Monotone white Chaos Chao, about level 30 in all stats; has won the ball for the Hero and Dark gardens. Completed all beginner races.
Heaven- Monotone red Angel Chaos Chao, lvl 57 in flying. Completed beginner races.
Swimmer- Fish Chao (Nuetral Swim/swim) level 92. As you may have guessed, very close to reincarnating. He has won the swim begginer and the Aquamarine Jewel.
Sonic- Monotone white Sonic Chao (Neutral Run/run) level 72; has won the run begginer and the Peridot Jewel. He won the Chao Garden ball, though Chaos 0 did the previous 3.
Aqua- Montone sky blue Sonic Chao, level 65 run. Won the run begginer.
NiGHTS- NiGHTS Chao phase 1 (Nuetral Fly/fly); just evolved, so lvl 15 fly. Has won the fly beginner race.
Sonic- My soon-to-be Sonic Chao, since the previous is a Monotone. Also just evolved, so level 13 run. He cleared the run begginer.
HERO:
Bluetip- This is my random, whatever-it-turns-out-to-be Chao. He turned out to be a Hero power type. I haven't really improved his stats since, but he's about level 15 in all sections. Has won all beginner races; named for his blue tips in childhood.
Fountain- Monotone red Hero Swim/Swim. Level 57 swim, won the swim begginer.
DARK:
REALA: REALA Chao phase 1 (Dark Fly/fly). Just evolved, level 18 fly. Cleared fly begginer.
Saber: Normal Dark Chao, about level 25 in all stats; named for the Boar's tusks he has.
There ya go.
