Latios didn't set the speed benchmark btw, 111 is just a really nice speed to have in a fast paced offensive metagame such as BW and BW2, keldeo, terrakion, latiAs, thundurus-t, garchomp, landorus-i when he was OU, etc.
will edit this post with my ninetales for 3 vote, don't bet on it though, I'm a lazy arse
also LOL @ LATIOS BEING BULKY, seriously, never use bulky latios, just use latias for that role, especially with you know a BAD defensive typing for the BW meta, ttar and dragons are everywhere, lets be honest, latios and latias have reasonably good if used right, but overall risky and high risk high reward defensive typings
technically the first data of latias in BW was programmed before latios (dex numbers and programmed time numbers wise), this is not relevant in any way, i just love that fact that it's not the first
