you mean OOO will be 3 headed...? the PSP screen is too small to actually see the medal details anyways...
if you're playing in the PSP version try this: use kiva emperor form and force your enemy to accept your final reflect invitation, you will see that the enemy rider will also be holding a zanvat sword:shakefist
i dunno if that works in the wii version too
also, keep doing ryuuki survive and odin's finisher and you will eventually see:
-the enemy placed wrongly so that the dragranzer shots his the ground BEHIND the enemy, making it a very hilarious finisher(especially because the shots are all there is to it, ryuuki doesn't ram the target at all, unlike knight survive's censored version)
-an uncensored version of odin's finisher where you can actually see odin, in firebird form, suicide ram the enemy(the very bright halo is obstructing it usually)
against a tag enemy, try landing a finisher while the enemy finished a tag and have not yet landed, when you succeeed, you will perform a finisher...against thin air, and it'll do no damage whatsoever IIRC
