What was Red trying to prove by attacking Oak, unprovoked and without warning? Would Oak classify as Red's "old teacher" figure. Red, having beaten every notable big wig in Kanto ever, finally decided it was time to go after Oak's head? Maybe he also wants to show Oak the walking time bomb the Charmander he gave to him turned out to be? Red's Mega Charizard looks almost demonic when it finishes mega evolving.
