Wotan, of the famous Project Wotan and subsequent playmat is named from the old Norse God Odin (Woden, Wotan, etc). I sometimes like to think about this card being named from the German tank operation in WW2 called Operation Wotan but alas, in Russia, Moscow captures you. Much like the ill-fated Battle of Moscow, Wotan is a sort of shiny massive barrier in the corpus of Bioroid Ice. Blue Sun: Powering the Future Decks might enjoy him with Oversight AI or Bioroid Efficiency Research but in the end, a 10 strength Barrier without many punishing effects doesn't really do much but offer a "wtf" moment when you rez him. Sadly, I love Wotan and as I have deemed him, "LORD OF THE ICE" I am a "wtf" moment lover.
