Twister: I see...in some way...my brother's friend Knuckles could relate...he guards the master emerald..it's like an "8th chaos emerald" in some cases...or 15th..but later on that, anyways he was fighting over it with some bat lady, and eggman tried stealing it for himself...but knuckles had to shatter it, thus he had to recollect all the shards...both that,. and 1 time we had some weird...water monster come out of the shattered emerald.... and it powered up with a chaos emerald whenever it had it..all 7 of them is basically a flooding apocalypse....

(he basically sums up sonic adventures 1 and 2)
