A dumb meme. It's kinda stupid...and by kinda, I mean very.
Like its one thing to have death of a hero figure be a prominent point in a show (Tamers: Leomon v Beelzemon...champion vs mega...okay sure.) to bring about tension and heavy emotion. But when its the same hero again and again and again...it loses impact.
Sure it is always sad because Leomon is usually well written or has a noble goal or whatever Savers did I can't remember, but the point of the matter is that there are other mons.
Angemon death and rebirth, biggest moment in the Devimon arc of the first season. Uh, there are other examples but my brain is still tired and I'm off on a tangent methinks. Whoops.
