The following Plasmids and Tonics are currently in use:

Plasmids:
Since The Scarecrow is part of the Saturnine he is a Houdini Splicer and uses these two Plasmids:
- Teleportation/Houdini Plasmid
- Incinerate!

Tonics: 
- Sports Boost
If his scarecrow cover is blown he usually tries to run and disappear.
- Human Inferno
To boost his fire power
- Extra Nutrition (+)
He uses this Tonic since he rarely eats at all [He can barely open his mouth since the splicing ended in some sort of lockjaw.]


In storage:
- Natural Camouflage
He loves playing/imitating a scarecrow, so he doesn't actually need that Tonic - though sometimes he does make use of it - for example if he pissed off someone and has to hide for a while.
