Design
RK-1 Has 2 Square's and 1 Triangle for it's base; 2 spawners which spawns 2 minions and has 2 Unique turrets at each sides, which could have been branched of Impactor, and 1 Streamliner barrel at the front and 2 Dual Machine barrels and 1 Unique Turret which looks like 3 Machine Guns stacked Barrel at its back for boosting the boss.

Technical
RK-1 Has low health and fast speed; its Streamliner bullets have normal damage, normal penetration, Fast bullets, High reload İts railgun bullets have high damage, high Health, medium penetration but in return low reload. however, its 2 minions have decent damage and decent penetration and they are not respawned instantly.

Countering
Although RK-1 may seem not very strong, it will still be a problem to kill. İf you are not using VPN you will most likely need a second player because this boss has very high firepower and can't be penetrated easily but if you are skilled; jump smasher branch or Knight is useful because you can jump to the boss's hitbox before it kills you or gets you under half health it will die because it has low health and normal body damage,
