The Suicide Squad actually make pretty good analogs for the late '80's Marauders. A while back I made some mods of Scalphunter, Riptide, and Sabretooth and put them on a 75th Deadshot dial, a Lashina dial, and a Bronze Tiger dial respectively. The Polaris/Malice mod went on a Manchester Black dial. Vertigo, Arclight, and Harpoon were put on Count Vertigo, E Knockout, and Captain Boomerang dials w/out modification. A sculpt from Martinex ended up on an unleashed Deadshot dial for Prism. I have a Blockbuster mod made, but it doesn't have a home yet, but will probably end up on a R Blockbuster dial. I even have a spare Amanda Waller dial waiting for a Mr. Sinister figure.
If you ignore a few things (like Vertigo flying, and Polaris/Malice not flying) it works really well, they even have a named keyword theme and a reasonably accurate TA.

Leech & the Power Pack are all some of my least favorites to bother with. Leech can do about as much damage to his own team as the opposing team. Wolverine is about the only appealing part of this to me & I don't have that version and he's got PLENTY of play options.

These "stinkeroos" still belong on the shelf IMO but once again, glad for those who do enjoy them.

But SI versions are great for my Doomy Daycare team with their crappy A/Vs and healing goodness for Doom when they are KO'ed.
