Blasters are an extremely aggressive weapon class and are only good at killing. When firing, one straight ball of ink flies perfectly forward, and explodes a said distance away from you. Blasters typically pack a punch, and the majority of them one shot. Blasters are also really slow, so missing a shot is a death sentence. Most blasters require support to get along, so a blaster partnered with a brella is a match made in heaven. Since blasters shoot out explosive shots, it can hit around or above walls. Trying to protect yourself from a blaster doesn't usually go to well, so you mainly have to kill them from a distance.
Luna blaster is very similar to the normal blaster. It comes with a slightly faster fire rate and a huge explosion hitbox, but it has bad range and ink efficiency. Its also got a good kit, which has splat bomb and zipcaster and is great at combating its bad range and speed, and make it a hard blaster to deal with.

Luna Blaster Neo has a solid kit. It has fizzy bomb and ultra stamp, the same kit as the custom goo tuber. This kit allows the Luna Blaster to be more mobile and supportive plus the extra chip damage from fizzy bombs makes its kit good.

Blaster is a really solid weapon. Pull the trigger to shoot out a one-hit blast (if you hit it directly on your opponent) or two indirect hits to destroy your opponent. Good thing this weapon has Auto Bomb to seek out opponents and blast them. The special is Big Bubbler which is great if you are under a lot of pressure (it's a shield). The only downside is its slow fire rate. So yeah, I'd say this is a really fun and solid weapon that I recommend.

The Custom Blaster is a more sneaky version of the blaster, with Point Sensor and Triple Splashdown. The kit wants you to hide in ink, and take advantage of unknowing people who walk by. If you miss a shot, use your point sensor to lock them into your entire team, and leave them as a target. Triple splashdown, on the other hand, use it when you are about to be punished. It works on the blaster, due to how many bad situations it can get in due to its slow speed.

Range Blaster is an extremely slow blaster but with a really good range and good damage. It has Suction Bomb and Wave Breaker, both making it even more aggressive. It is terrible at covering turf, so go with getting as many kills as you can get. A thing I like to do is to play with somebody who plays Tenta Brella, hide behind their gigantic shield, and then get 5283785247 kills.

CRB is back with its iconic splat bomb and Kraken. This kit is perfect; it's amazing how good it is. The splat bomb is super helpful with chip damage, making kills easy to get. Kraken is great to use while under pressure or when the enemy team is cornered. Overall, this weapon is great, and I would recommend it.

Clash blaster is a super fast blaster that is weak and has bad range. It's really good on tower control, due to its kit. It has Splat Bomb and Trizooka, a very aggressive kit. It's okay at killing and is one of the worst weapons in Splatoon. But it's still fun. To play it, try to get kills by abusing its AOE.

Same thing as the Clash Blaster, but it has curling bomb and super chump. This makes for a fun kit and is my favorite blaster. Use curling bomb if you want to get quicker kills, and also use it to cover turf. Super chump on the other hand isn't that good. Try to lure people into the mess of projectiles, to also get plenty of enemy wipeouts.

Rapid Blaster is a good drag-down defense weapon. It's great at overwhelming people and slowing them down, to then shoot them a whole bunch and kill them. Rapid blaster also can't one shot, so landing 2 directs or 3 indirects should be able to kill. Its kit is Ink Mine and Triple Inkstrike and is solid overall.
-Max
Rapid blaster deco is the best blaster in the game (for splat zones but it's actually good for all modes). It thrives in pushing, killing, and being aggressive overall. I highly recommend this if you lean more towards blasters. It's kit is Torpedo and Ink Jet, which is just amazing on this weapon.

Rapid blaster pro is a slower and more costly rapid blaster with more range. Its great at poking but is weak to being rushed down. Its kit is great at support and can also help with being aggressive, and it is Toxic Mist and ink vac. Remember to use ink vac effectively, and abuse the easy shots to land from Toxic Mist.
-Max
Rapid Blaster Pro Deco is weird and is focused on ranged combat. Its kit is good and has angle shooter and killer wail. It's essentially a sniper blaster, so try to get up high and snipe people.
-Max
S-blast is a fun blaster that has really good range but lacks in speed. This weapon has the unique ability to change modes when you are in midair, decreasing your range and increasing the size of the explosion. Its kit is good at support, has Sprinkler and Reefslider, and works well. I would recommend trying out this blaster

This weapon has a great aggressive kit, including Burst Bomb and Booyah Bomb. Using a Burst Bomb directly after firing is an almost guaranteed kill combo, and gives the weapon more ranged pressure. Booyah Bomb is overall great for the weapon. Use it for turf, use it as a panic button, heck, just throw it in the enemy base because why not.
