Sonic Boom is an enemy ability that can be used with 
Enemy Skill Materia in Final Fantasy VII Rebirth. It deals 
Wind damage to an enemy, and grants 
Bravery and 
Faith to the user. It is the default ability of the materia.
Obtained[]
Sonic Boom is the default ability of Enemy Skill materia, and is granted upon completing the initial challenge, "Biological Intel: Know Thine Enemy", that grants the materia.
Use[]
Sonic Boom is used both to temporarily buff the caster by granting them bravery and faith, boosting their attributes temporarily, while also dealing some wind damage. It can be used to remove 
Debrave and 
Defaith without needing 
Esuna.
The ability to buff the user with both bravery and faith is greatly beneficial. This means both that the ability is more ATB-efficient than casting Bravery and Faith, and that the party member does not need to equip an 
Empowerment Materia to apply these statuses to themselves (only to apply to others). These statuses have a much shorter duration when applied by Sonic Boom compared to the Bravery and Faith spells, but are still a great way to quickly boost damage output, and the fact that both apply mean Sonic Boom can be useful both for physical damage dealing party members and spellcasters.
The damage dealt is fairly modest, and not comparable to similar wind damage abilities (such as the Wind Materia spells, or Tifa's Reverse Gale). If wind damage can pressure an enemy, or an enemy is otherwise weak to wind, this is an added bonus to the ability. However, it is primarily used to buff the user.
