This is probably from mid-to-early high school. I tried to draw as many of my Sonic fan character/anthro characters as possible. This is the first (and so far, only) time I have attempted such a large cast picture. Since then, some of these characters have been abandoned, many more have been created, and most of the ones pictured here have had design changes.

Front row, left to right:

1. Yellow female echidna: Door Into Summer McKay/Echidna
2. Black and tan hedgehog/lion: Benign Elijah Vires
3. Black-clad skunk: Monty Law
4. Dreadlocked zebra: Solomon Miller
5. Small green snake on Solomon's dreadlock: Euphoria (female)
6. Female zebra: Sheba Miller, Solomon's twin sister
7. Hero chao: Bedlam (female)
8. Yellow flying squirrel: Rebound

Middle row:

9. Robot pirate hedgehog: Captain Ironspine
10. Vulture: Bafan X.
11. Black hedgehog/lion: Officer Jeremiah Vires, Benign's father
12. Brown hedgehog/lion in African prints: Hibiscus Cetera, Benign's older sister
13. White hedgehog: Lanny Cetera, Hibiscus' husband (Bedlam the chao is his pet)
14. Brown hedgehog in suit and tie: Bruce Cetera, Lanny's brother
15. Brown hedgehog/lion in green, yellow and red T-shirt: Peter "Cease" Vires, Benign's cousin

Back row:

16. Black hedgehog/lion in hammock: Paul "Sekkle" Vires, Benign's cousin. His hat ended up somewhere by Monty and Solomon's feet.
17. Brown hedgehog in green dress: Dr. Desdemona Vires, Benign's mother
18. Brown and tan cat with lightning bolt: Shadowcat or Shadow. Both names are taken anyway. She was my first Sonic fan character/anthro character, made when I was about nine.
19. Yellow hedgehog in gray suit: Daniel Cetera, Lanny and Bruce's father
20. Magenta rabbit/fox/cat/whatever: Clarrissa Kaiyah, made some time in late grade school.
