Blanka Guide & Overview

Cons

• Weak and inconsistent conversions: Blanka's easiest-to-use main combo ender, Electric Thunder, is prone to whiffing at further ranges. This means that Blanka is very reliant on having a charge to get a reward for his pokes. Blanka's common BnB combos also lack substantial damage without Install or overdrive to spare.
• Limited Setplay: Blanka-Chan Bomb is an invaluable tool enabling his aforementioned Setplay specialty. However, Blanka only has 3 of them available every round. If a Blanka player uses the move recklessly or predictably, opportunities to secure the round may be lost.
• High-Risk Gameplan: By the nature of his toolkit, Blanka takes a constant, high risk when using his variety of tools - many of his specials have a very long startup and are easily punished unless used carefully. His infamous Blanka balls, while tricky, are all very unsafe on the block (and potentially even punishable). Many of his normals tend to be slower on average to startup and recover, and many of his important tools against fireballs (3HP, coward crouch, 6HP), are highly unsafe.
• Inconsistent anti-air DPs: While his anti-air normals are good, his dedicated anti-air specials, Vertical Rolling Attack (or Vertical Blanka Ball) have an issue of simply missing the opponent if executed too close/far. While this can be mitigated by using the right versions at the right distances, it still leaves a significant chance for error, especially in distances where it is unclear which version will hit the opponent.
