Pokedex Entry:
"Mega Typhlosion vents excess power in explosive bursts, then draws the released heat and static back into its core. This feedback process rapidly restores its strength whenever it withdraws from battle, allowing it to return moments later with renewed ferocity."
If Meganium and Feraligatr got Mega Evolution, then Typhlosion should also get it as it's the only one of the Johto starter final forms not get one instead Typhlosion gets a regional form introduced in Hisui instead.
Mega Typhlosion details:
