Roblox Slenders are boys who are usually very tall, you can find them in games such as Animations: Mocap and Ragdoll Engine. Their names usually start with J. Some of them also have an online girlfriend, which is usually a copy and paste.

They also have TikTok. They usually wear, beautiful hair for beautiful people, clean black spikes, roblohunk hair, a plain black shirt, plain black pants, stitchface (rich ones usually wear korblox and playful vampire), etc

some of them are also girls trolling sometimes.
