Exploud

As a Pokemon with no STAB movesets and lackluster stats, there's nothing going for Exploud. It looks pretty cool, though.

Best PvE Offensive Moveset

• Bite’s higher DPS is better than Astonish’s higher energy gain.
• Crunch shares type coverage with Bite and Astonish.
• While Fire Blast is poor on offense, Disarming Voice and Return* are plain awful.
• Boomburst has the highest neutral performance, but why would you use Exploud for neutral performance...?

Best PvE Defensive Moveset

• Astonish beats Bite with higher power, energy gain, and better neutral coverage.
• Crunch has 3 bars and an early damage window, although it’s poor vs. Fighting.
• Disarming Voice has 3 bars and superior type coverage, but it’s easy to dodge.
• Return* is very hard to dodge, has 3 bars, and gets STAB, but its base power is extremely low.
• Fire Blast has no redeeming defensive qualities aside from hitting Steel Types for Super Effective damage.
• Boomburst has high neutral damage, but will probably never get a chance to launch.

Exploud is a Normal-type Pokemon and lacks STAB on any of its relevant moves. Astonish is the stand-out Fast Move option, as it sports solid damage and slightly above-average energy generation alongside good neutral coverage. 

The insane energy cost of Fire Blast results in only two charge move options: Crunch and Disarming Voice, both of which have identical stats. The former is a Dark-type move that synergizes with Exploud's fast moves to counter Ghost and Psychic Pokemon, while the latter is a Fairy-type move which can be useful to cover Exploud's weakness to Fighting-type opponents.
