I think the West Edmonton Mall sent their 4 submarines to the scrap heap 2 years ago.
Weapon K? You mean the secret Department K project? I know Tigerstryke's electro-magnetic suit was based on Guardian's suit so I figure he can teleport.
Not sure about the other members of Department K / Weapon PRIME. It's one thing to teleport yourself and another person but I don't think Guardian, or Vindicator, or TigerStryke can teleport an 85 story building from Toronto to Ottawa.
