create implication dead_or_alive_5 -> dead_or_alive

Link to implication

Series.

Similarly:

create implication dead_or_alive_2 -> dead_or_alive
create implication dead_or_alive_4 -> dead_or_alive
create implication dead_or_alive_xtreme -> dead_or_alive

Don't see the point of keeping the Dead or Alive sequel tags (or any fighting game sequels) since they do little more than categorize the characters they introduced.

We should probably take a look at the fighting game tags, yes. It might be better to change them to "only use sequel tags if an outfit, character, or artstyle refers to a single game or if it's a lineup for a specific game"

Agree it could take some looking at, but as long as they exist, done the four implications.
