I bought this for Guardian Heroes, I have no idea what the other series shown at the end are.

These pages are for Goddess Athena from the game "Athena" (1986), prior to her inclusion/descendant/reincarnation(?) as Athena Asamiya in SNK's King of Fighters (1994 onwards).

The tentacle alien here is Mars People (not person) from SNK's Metal Slug series, indicating the short is based on SNK vs Capcom Chaos, a crossover fighting game that featured Mars People and Goddess Athena (not KOF Athena) as playable characters.
