Not required to be anything serious, just... Things he can do. Techniques he can pull off. Did anyone know that side or up grab + C4 + fullcharge mine (both on a platform, can up b for cypher, down b to cancel the cypher and send out a c4) can equal 50% damage and/or instasmash for Snake? You can pull it off on most courses if done correctly, and you can even upsmash after doing it, or use an upsmash to launch the opponent instead for extra power (Bowser can be very victim of this). It has trouble on the smallest characters if you use it on an up throw (grabs can be annoying for those chars), but it's a glee to do it and I've found can work well. Works even at 30%-50%, hard to execute. I also find that mines are useful finishers to combos too.
