1. Robotnik's bad an' Sonic's good...'nuff said.
2. Robotnik's secretly jealous that Sonic can eat as much as he wants and not
get fat.
3. Sonic's jealous that Robotnik can grow a mustache so easily (he's secretly been
trying to grow one for years to impress Sally).
4. Robotnik's jealous that there are more Sonic shrines on the 'Net than Robotnik
shrines.
5. Hey, if someone insulted you every day and foiled all of your painstakingly made
plans, wouldn't you be mortal enemies with them too?
6. Um...gee...Robotnik's trying to destroy Sonic...maybe that has something to
do with it...
7. *submitted by Sonic12321@aol.com* Let's think about that....you're smart....aren't you? Using friends as
science experiments and polluting your home. Not to mention exiling your girlfriend's father to some unknown dimension while calling you "rodent" and vowing to wipe you from the face of the earth while at the same time dictating your girlfriend's family's rightful thone. And don't think turning your last known
relatives into mindless slaves doesn't have any thing to do with it. Not to mention using your one, your love, your all as bait countless times. Not to mentoin having an entire zip code to them self (he he) and turning your beloved and beautiful city into an metallic industrial nightmare. You'd probably be mortal enimies with them, I'll bet.
8. *submitted by Go Ryusuke* Because their not immortal.
9. *ditto* Sonic is allergic to eggs.
10. *ditto* Robotnik can program a VCR, and Sonic can't.

12. *ditto* Sonic borrowed Robotniks Spice Girls CD and never returned it.
13. *ditto* Secretly Robotnik is madly in love with Sonic.0.o' Heehee, dis one funny.=)
14. *submitted by Justin Reese* Sonic couldn't shoot the broad side of a barn. (I'll prove it too! Watch
the weekday series of Sonic the Hedgehog on UPN early in the morning.)
15. *submitted by Justin Reese* One insult right after another. "Yo' Ro-butt-nik! Cool jammies!" Japan
insults Robotnik too by calling him "Eggman."
