Stylized Roblox Enemy Mob Models for a Tower Defense Game

I’m building a tower-defense experience in Roblox and I need fresh enemy mobs that feel instantly recognisable and full of personality. The priority is high-quality modeling in a cohesive stylized look, then clean rigs, game-ready animations, and punchy in-engine VFX that sell each creature’s attacks and death.

You’ll be creating brand-new assets, not touching free models, so your own artistic flair is important. Roblox Studio is the final destination, but you can sculpt in Blender, Maya or any tool you’re comfortable with as long as the meshes import flawlessly and stay within platform performance guidelines.

SCOPE — 6 ENEMY ARCHETYPES
For each, I need a game-ready mesh, an R15 rig, one animation, and the crystalline energy VFX/some effect flairs on them to make them each shine (needs to be somewhat subtle). Animation per mob:

Basic Xor (Riftborn) — Standard size — Walk
Swift Xor (Voidrunner) — Slim — Run
Brute Xor (Worldbreaker) — Large/bulky — Walk
Swarm Xor (Shardspawn) — Small, floating unit — Fly/hover
Armored Xor (Bulwark) — Standard size — Walk
Ranged Xor (Starpiercer) — Standard size — hover + cape/flowy animations

ANIMATION REQUIREMENTS (IMPORTANT)

Exactly one locomotion animation per mob: walk for most, a run cycle for the Swift Xor, and a fly/hover cycle for the Swarm Xor. The way they will walk, fly, or run will be very important as this is the only animation that's included in them.

No death animations, no attack animations, no idle/combat animations. Locomotion only.

TECHNICAL REQUIREMENTS (NON-NEGOTIABLE)

Roblox-ready, rigged to the R15 humanoid skeleton so animations retarget cleanly.
Low-poly, optimized for low-end Android — this is the binding performance constraint. Rough target ~2,000–5,000 triangles depending on size class (Brute higher, Swarm lower); final budget to be agreed.
Textures at 512x512.
EmissiveStrength = 0 — no baked emissive maps. All glow is handled in-engine via Neon material parts and Roblox VFX (ParticleEmitters / Beams / Trails). The signature violet-purple glow and crystalline energy effects should be delivered as in-engine Roblox VFX setups, not painted into the texture.
Delivery as .fbx + textures and/or .rbxm Roblox models; animations delivered as importable .fbx or uploaded Roblox animation assets.

I've included an AI mockup as a target reference for the models. Only one thing will change will be the swift mob.

Communication and urgency is highly important to me. If you communicate well, create high quality models quickly, then there will be plenty of additional projects we can work on moving forward as this can be a longer term position based on your work.
