Kay/O tier 9 : Memory Log

Brimstone tier 9 : No one left behind

​

Both of the player cards have similar silhouettes, Brim's being more clearer with what looks to be him carrying presumably Kay/O, him being a human or a machine is up for debate, but I think these two are connected in some way because in Kay/O's trailer it can even be seen that Brim is the only one in Kay/O's side.
